Title: Nuclear reactor recirculation pump
Inventor: MIYANO HIROSHI
IPC: F16J15/447
Filed: 1990-04-13
Abstract: PURPOSE:To relieve thermal stress by providing a labyrinth seal part with many labyrinth grooves and mixing grooves which have larger spaces at least either of a casing cover and a pump shaft. CONSTITUTION:Many labyrinth grooves 14 for obtaining specific flow passage resistance are formed in the inner peripheral part of a casing cover 4 and several mixing grooves 15 which have larger spaces than the labyrinth grooves 14 are arranged at equal intervals. When the mixing grooves 15 are formed, the flow rate increases and purging water which enters a cylindrical flow passage 13 flows the 1st mixing groove 15 and stays therein, so that cold water and hot water are mixed. Consequently, the temperature of the purging water approximates to the temperature before the flow rate increase speedily and their temperature difference decreases greatly as compared with a conventional temperature difference DELTAT1. Therefore, thermal stress generated in the structure material of the labyrinth part is relieved and the safety is improved.

Title: Color electrophotographic method
Inventor: ISHIDA TSUTOMU
IPC: G03G13/01
Filed: 1979-07-30
Abstract: PURPOSE: To make possible two or three color copying through one image exposure by using a photoreceptor laminated with three kinds of photoconductive layers of different photosensitive wavelengths.  
     CONSTITUTION: If a photoreceptor 1 laminated with three kinds of photoconductive layers 3W5 of different photosensitive wavelengths formed by amorphous selenium, eutectic complex of thiapyrilium salt and polycarbonate and β type copper phthalocyanine is subjected to red color irradiation and primary charging, the layers 3, 5 are made conductive, and positive and negative charges appear on the top and under of the layer 4 respectively. When it is next subjected to secondary charging in a dark place, the layers 3W5 are of high resistance in the dark; therefore the surface of the layer 5 and the boundary of the layer 3 and the conductive substrate 2 charge themselves to negative polarity. When image exposure is performed in this state, the surface potential of the layer 5 does not change with respect to the black image portion and the surface potential inverts to negative polarity only for the red image portion of the original, thus two color images of red and black are formed by the positive and negative charged red and black toners through one exposure. In a similar manner, the three color images of red, black and blue may be formed through one exposure without any image deviation.
